I use Seventh Gate at work to share the LAN connection over WiFi to my phone. The problem is some of my colleagues have come to know about this and request the WiFi password and I cannot deny them! So now 5-6 users are using this WiFi and choking my bandwidth.
Is it possible using any application to block specific MAC addresses from connecting to my laptop? OR
Is there an alternative to Seventh Gate that provides this feature?
I use Avast Internet Security 6 but was unable to find any setting related to this.
